YH-699 rotating 3D Christmas tree with 5 LED Bluetooth speaker DIY parts

The YH-699 rotating 3D Christmas tree DIY soldering kit is based on the 51 microcontroller. After assembly, it forms a layered 3D Christmas tree shape, equipped with colorful LED beads, enabling dynamic lighting changes and overall rotation. It also integrates Bluetooth speaker functionality. The kit includes a Christmas tree PCB board, a transparent acrylic shell, and all electronic components. It’s a two-in-one DIY kit combining microcontroller training and soldering practice. Once assembled, it’s a rotating, sound and light-emitting technological ornament that can also connect via Bluetooth to play music. Suitable for electronics courses, holiday crafts, etc.

Product features:

1. 3D assembly structure: Multiple Christmas tree PCB boards are assembled into a single piece, paired with a transparent acrylic shell base. The finished product has a strong 3D effect, and the shell protects the internal circuitry and enhances its aesthetic appeal.
2. Colorful dynamic lighting effects: Multiple colored LEDs, controlled by a microcontroller, enable various lighting modes, creating a dazzling and atmospheric effect.
3. Automatic rotation function: Driven by a base motor, the entire Christmas tree slowly rotates, displaying lights at multiple angles for enhanced visual appeal.
4. Integrated Bluetooth speaker: A built-in Bluetooth audio module allows for music playback via Bluetooth pairing with a mobile phone, creating sound and light effects in sync with the music.
5. 51 microcontroller training platform: A complete microcontroller practice project, allowing practice in soldering surface mount/through-hole components and familiarizing oneself with 51 microcontroller hardware circuits.
6. Holiday creative DIY project: Once soldered and assembled, it can be used as a Christmas desktop decoration or a handmade gift.
